BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flash panel used for wall materials, partition materials, door materials and the like.

[0002]

2. Description of the Related Art In a conventional flash panel, sawn wood such as spruce, hemlock, pine, and lauan or particle board is used as a core material, and plywood and decorative plywood are attached to the front and back surfaces thereof.

It has also been practiced to form a groove having a patterned pattern on the front surface and / or the back surface of such a flash panel.

[0004]

However, in the conventional flash panel as described above, when the sawing material is used as the core material, the hygroscopic expansion in the fiber direction of the sawing material and the direction orthogonal to the fiber direction of the sawing material Since the ratio was different and the material was not homogeneous, the flash panel was apt to warp or twist.

Although this problem is solved when particle board is used as the core material, the paintability between the plywood and the core material is improved in both cases of using sawn wood and using particle board. Because of the difference, it was necessary to carry out thick coating or edging of sheet material such as vinyl chloride, resulting in low productivity.

Further, in the conventional flash panel in which the uneven pattern is formed on one surface or both surfaces of the flash panel, since a thin plywood is generally used, it is not possible to form a deeply engraved pattern, resulting in decorativeness. It was scarce.
Of course, if thick plywood is used, this problem can be solved, but the weight of the flash panel itself increases and the cost also increases.

It is possible to arrange the core material at the position where the groove is to be formed and form the groove extending from the surface to the core material, but there is a difference in material between the surface of the groove and the plywood surface. As it is, it does not look good, and when applying paint, ride paint,
It was not possible to obtain a uniform painted surface due to the difference in suction condition. Thick coating can be applied, but productivity is poor and coating costs are high.

Further, the same problem arises when chamfering the mouth of a flash panel.

[0009]

The present invention was devised with the object of solving the above-mentioned problems of the prior art, and a panel is attached to the front and back surfaces of a core material assembled in an arbitrary arrangement. In the flash panel, the core material is a composite material in which a wood fiberboard is laminated on one or both surfaces of a board material different from the wood fiberboard as a base material, and the panel is formed of the wood fiber board, and the panel Is characterized in that a chamfered portion reaching from the core material to the portion of the wood fiberboard on the surface of the core material and / or a groove having an arbitrary pattern is formed.

Any coating can be applied to the surface of the chamfered portion and / or the groove.

By forming one of the wood fiberboard forming the panel and the wood fiberboard of the core material surface part with the softwood wood fiberboard and the other with the hardwood wood fiberboard, the difference in color tone between them Even when a single paint is applied, different colors are obtained, and the designability can be improved.

The panel and the surface of the core material may be made of the same quality wood fiberboard. In this case, it is possible to give different colors to both by the dyeing process performed in advance, and to give the same effect as the above.

[0013]

In the flash panel of the present invention, the panel is made of wood fiber board, and the core material is made of a composite material in which wood fiber board is laminated on one or both sides while using a board material different from the wood fiber board as a base material. , Because the wood fiberboard is homogeneous,
Do not warp or twist the flash panel.

Further, even if the wood panel of the flash panel is chamfered from the panel to the wood fiberboard portion of the surface of the core material, it has a good appearance because it is made of the same material, and even when it is painted, it is uniform. You can get a nice painted surface.

Further, a core material is arranged at a position corresponding to a three-dimensional pattern to be formed on one side or both sides of the flash panel, and the core is assembled. By forming the concave groove having an arbitrary pattern reaching the portion, the finish can be improved even if thin coating is performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a flash panel 10 according to an embodiment of the present invention. In this embodiment, the core material 1
Although 1 is shown as core-shaped in the shape of a day, it is not limited, and core-shaped in any shape such as a square shape and a square shape.

The core material 11 is a composite material in which a plate material different from the wood fiber board is used as a base material 11a and a wood fiber board 11b is laminated on one surface thereof.

Wood fiberboard 11b forming the surface of the core 11.
Is provided with a thickness corresponding to the depth of the groove or chamfer formed on the surface or the wood mouth, that is, the groove or chamfer is provided in the portion of the wood fiber board 11b in the core 11.

The base material 11a forming the back surface of the core material 11 is made of a plate material different from the wood fiber board, such as sawn wood, plywood,
Laminated wood, veneer, laminated veneer, particle board, synthetic resin board. Further, a laminated material obtained by laminating a plurality of these may be used.

Panels 13 and 13 are attached to the front and back surfaces of the core material to form a flash panel 10.

The front and back panels 13 of the flash panel 10,
13 and the wood fiber board forming the surface portion 11b of the core material 11,
For example, a hard fiber board or a medium fiber board may be used. Although not essential, the specific gravity of the fiber board is preferably 0.4 to 0.8.

The wood fiberboard used for the panels 13 and 13 may be provided with a decorative sheet material such as a decorative paper, a decorative cloth, a synthetic resin decorative sheet or the like on the surface thereof, or an optional makeup such as color coating is applied thereto. it can.

The core 11 may be assembled by a usual method, but when chamfering the wood mouth portion or from the panel surface, the core 1 is assembled.
When the concave groove reaching the surface wood fiber board 11b of No. 1 is provided, the core assembly is performed so that the core material is positioned in those processing areas.

Thus, in the flash panel shown in FIG. 1, since both the panels 13 and 13 and the surface portion 11b of the core material 11 are made of wood fiberboard, expansion and contraction due to moisture absorption and desorption are synchronized in these layers. The product does not warp or go out of order.

FIG. 2 shows a state after chamfering the grain of the flash panel shown in FIG. A coating 17 is further applied to the chamfered portion 15.

Since both the surface panel 13 and the core material surface portion 11b are made of wood fiberboard, the chamfered portion 15 has only a linear adhesive surface to which they are adhered, which is almost obtrusive. In addition, since the materials are the same, the finished state when the coating 17 is applied is also good.

3 and 4 show a concave groove 19 which reaches the core material surface portion 11b in a V shape along the core assembly on one surface of the flash panel similar to the flash panel 10 shown in FIG. An example in which the

Both the surface portion 11b of the core material and the panel 13 on the surface are made of wood fiber board, and the concave groove 19 is formed in the panel 13.
Since it is engraved so as to reach the core material surface portion 11b from the core material, the adhesive surface thereof is only linearly formed in the concave groove 19 and there is no discomfort in appearance.

FIG. 5 is an enlarged view of a state in which coating 21 is applied to the exposed surface of the concave groove 19. For the same reason as in the embodiment shown in FIG. 2, a good finished state can be obtained without applying thick coating.

Although some embodiments of the present invention have been illustrated and described above, the present invention can take various modifications without departing from the technical idea thereof.

For example, the core material does not necessarily have to be core-assembled, and may be a panel body in which a wood fiber board is attached to a base material made of a plate material other than the wood fiber board.

A composite material in which a wood fiberboard is laminated on both sides of a base material made of a plate material different from the wood fiberboard may be used as the core material.

Arbitrary actual processing can be applied to the surface of the core material.

Arbitrary makeup such as edging, dyeing, and painting can be applied to the mouth of the flash panel.

The chamfered portion and the concave groove can be formed on both sides of the flash panel, if necessary.

[0036]

According to the present invention, since the panel and the surface portion of the core material are both made of wood fiberboard, the flash panel is hardly warped or deformed.

When the chamfered portion or the concave groove is formed on the surface of the flash panel, it is formed so as to have a depth reaching from the panel to the surface portion of the core material. There is no feeling of discomfort, and even coloring and coating are possible, and the finished state is also good.

By appropriately selecting the material, color and the like of the wood fiberboard used for the panel and the surface of the core material, it is possible to manufacture a product having a variety of design characteristics.

Since both the panel and the surface of the core material are made of wood fiberboard, chamfering, routing and the like are easy and the finish is good.

Furthermore, since a plate material different from the wood fiberboard is used as the base material and the composite material obtained by sticking the wood fiberboard on one or both sides is used as the core material, it is necessary to use a good material as the base material. Therefore, the manufacturing cost can be reduced.
